SPECIFICATION formingpart of Letters Patent No. 713,283, dated November11, 1902. Application iiled December 12, 1901. Serial No. 85,670. (Nomodel.)

To all whom t may concern.-

Be it known that I, JAMES BROWN, a citi- Zen of the United States,residing at the city of Pawtucket, in thecounty of Providence and Stateof Rhode Island,'have invented cer-v tain new and useful Improvements inSpinning-Machines, of which the following is a specification.

My invention relates to certain parts in the construction of a frame fora spinning-machine; and the object of my invention is to provide meanswhereby the centers of the spindles are readily 'adjusted to an exactplumb position on the frame and transverse of the machine.

A further object of my invention is to provide means whereby thespindle-holsters have adjustment longitudinally of the frame of themachine.

My invention consists in the combination, in a spinning-machine, of oneor more transverse frames intermediate the end frames of the machine,each of said transverse frames divided across, so as to leave a lowerstationary portion, means for securing each of the said transverseframes at their points of division, two bars extending longitudinallyupon each side of the machine, situated in a vertical plane one abovethe other and secured upon the upper portions of each ofsaid transverseframes and end frames, respectively, the upper two of said bars beingprovided with a groove extending longitudinally from either end thereof,a series of holsters mounted upon the upper bars of said frames andprovided with spindles, each of said bolsters having a rear extension atits top and bottom thereof, the top extension of said bolsterterminating with a tongue to engage in the groove of said bar and thebottom extension provided with a screw-threaded opening to receive aset-screw to impinge against the bottom edge of said bar and hold saidbolster in position upon the same, and means intermediate each oppositeupper portion of the said transverse frames to permit of adjusting thecenters of the spindles to a vertical plane on the machine, inthe'manner as hereinafter fully described, and specifically pointed outin the claims. l

In the accompanying sheets of drawings, Figure l represents a partialside elevation ot a spinning-machine embodying the several parts of myimprovement. Fig. 2 is a central vertical sectional View of the clampingarrangement for cachot' the divided sections Yof transverse frames ofthe machine, taken in line W W of Fig. 4. Fig. 3 is a'front sectionalelevation view of the clamping device, taken in line X X of Fig.^2. Fig.4 is a transverse sectional view of the spinning-machine, taken in lineY Y of Fig. l. Fig. 5 is a partial top plan viewof one side of thespinningmachine. Fig. 6 is a sectional view illustrating the means forsecuring the bars to the end frame of the machine, taken in line Z Z ofFig. l; and Fig. 7 is a plan view of one of the traveler-rings.

Similar letters of reference indicate similar parts in the diderentviews of the drawings.

As well known in this class of machines, the spindles inv revolving at ahigh rate of speed frequently get out of plumb and necessitate theplacing of felt or cardboard beneath the bolsters,thus requiringconsiderable time on the part of the operator to make the spindles runtrue. The principle of my improvement is to obviate this difticulty,whereby a ready means is quickly afforded to bring the spindles to anVexact vertical or plumb position upon the frame of the machine.

Referring to the drawings, A designates one of the end frames of themachine, and B B the transverse frames,rsituated opposite to each otherand comprising one or more sets intermediate the end frames ofthemachine, and said transverse frames are divided across, as at pointsct ct in Fig. 4, to provide lateral movement of the upper portions upontheir lower portions that are held in a fixed position by bolts ct' a',and each of the divided sections of transverse frames are connectedtogether by bolts b b, that project through elongated slots c c, formedin plates d cl, located upon each side frame B B in the manner as shownin Figs. 2, 3, and 4. Integral with the tranv'erse frames B B,`at theupper portion thereof, are inwardly-extendin g arms e e, each of whichhas a U-shaped end portion to receive the screw-threaded end portions ff of a rod o, and this rod is secured within the U-shaped end portion ofthe said arms by nuts g g, that impinge against washers 71, h,interposed between said nuts and IOO said portion of the arms,respectively, as shown in Fig. 4.

D D' are two flat bars extending horizontally upon each side of themachine and rigidly secured upon each upper portion of the saidtransverse frames by bolts b' b. These bars extend from the end framesof the inachine located in a plane one above the other, and each bar ismade alike, with the exception that the upper bars D D are each providedwith agroove 1l in its top edge and extending the full length of thesaid bar. The ends of the bars D and D' are secured upon anglepiecesjjby bolts la k, and these pieces have one of each of their extensionsprojecting from the said bars and provided with a slotted opening Z toreceive a bolt k, that secures the ends of the bars by their anglepiecesto the end frames of the machine in the manner as shown in Figs. 5 and6.

E E are the bolsters, having the usual spindies m m, provided withwhirls n n, that are driven by the cylindero in the ordinary way, andeach of these holsters has an upper rear extension p, with adownwardly-projecting tongue at its extremity, as p', to engage in thegroove 't of the bars D D, and the lower ends of the holsters have arear extension p2, that is provided with a screw-threaded opening toreceive a set-screwp3 to impinge against the bottom edge of said barsand hold said bolsters in position upon the same.

Having described the different parts of my improvement, I will proceedto explain its operation. Referring to Fig. 4, when one or more spindleshappen to get out of plumb during the running of the machine-say on sideNo.1-the bolts bb and bolts lr. 7c of the frames A and B, respectively,are unscrewed a trifle, after which theAouter nut g of the cross-rod Cis then unscrewed to allow of screwing forward the next inner nut g andforward the upper portion of the frame B upon the top edge of it-s lowerfixed portion and carries the centers of the spindles to their normal orplumb position on the machine, after which the aforesaid nuts and boltsare screwed up and firmly hold the respective parts in place. After thespindles are so adjusted the traveler-rings q q are moved outward uponthe rail 0', said rings having lateral movement on the rail byset-screws r r', that enter the rail from slotted openings r2 r2, formeddiametrically opposite each other in the circular base of the rings, asseen in Fig. 7, and when they are concentric with the centers of thespindles the said screws 7 r are turned to hold the' rings firmly inposition.

Having described my improvement, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a spinning-machine, the combination, of one or more sets oftransverse frames intermediate the end frames of the machine and eachset of transverse frames divided across so as to provide a movable upperportion upon a ixed lower portion, and each of said upper portions offrames having an inwardly-extending arm integral therewith and providedwith an opening, a rod mounted in the opening of the arms of said framesand provided with an exterior screw-threaded surface at each endthereof, nuts engaging the threaded portions of said rod and adapted toimpinge against each side of said arms to hold the upper portions offrames in position, means for securing the said transverse frames attheir divided portions, two bars rigidly mounted upon the upper portionsof said transverse frames and extending,r longitudinally upon each sideof the machine and in a vertical direction with each other, the upperbar of each set being provided with a groove extending the full lengththereof, means to secure each opposite end of said bars rigid to the endframes of the machine, a series of spindle-holsters having a rearextension at their top and bottom ends, the top extension of saidbolster terminating with a tongue to engage in the groove of said upperbar and the bottom extension provided with a screw-threaded opening,with a set-screw to enter the threaded opening of said bolster toimpinge against said upper bar, and hold the bolster in position uponthe same, as set forth.

2. In aspinning-machine, the combination, of one or more sets oftransverse frames intermediate the end frames of the machine, each ofsaid transverse frames divided across so as to leave a supporting lowerportion that is held in a fixed position, means for securing the saidtransverse frames at their points of division, a bar rigidly securedupon the upper portion of the said transverse frames and extendinghorizontally upon each side of the machine, said bar provided with agroove in its top edge and extending the full length thereof, a seriesof spindle-holsters mounted upon said bar, each bolster having a rearextension at its top and bottom thereof, the top extension of whichterminates with a tongue to enter the groove of said bar and its bottomextension provided with a screw-threaded opening to receive a set-screwto impinge against the bottom edge of said bar and hold said bolster invertical position longitudinally of the machine, a spindle mounted ineach of said bolsters, with means mounted between the upper portions ofsaid transverse frames, to move the same inwardly or outwardly upontheir lower lixed portions and adapted to bring the centers of the saidspindles to a vertical position, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES BROWN.
